1. 1. Multi-Band Multi-Standard CMOS Receiver Front-Ends for 4G Mobile Applications

   Författare :Saul Alejandro Rodriguez Duenas; Ana Rusu; Mohammed Ismail El-Naggar; Erik Bruun; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; LNA; mixer; 4G; Electronics; Elektronik;

   Sammanfattning : The development of the transistor and its continuous down-scaling has allowed during the last decades the appearance of cheap wireless communication systems targeting consumer products. The complexity of these systems has increased dramatically during the last years, mainly fueled by both the Moore law and improvements in communication theory. LÄS MER

3. 2. Sigma-delta based techniques for future multi-standard wireless radios

   Författare :Steffen Albrecht; Mohammed Ismail Elnaggar; Franz Dielacher; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electronic structure; Elektronstruktur;

   Sammanfattning : Improvements in process technology and design innovations have resulted in compact and cost effective digital baseband solutions. The radio part, however, has remained a bottleneck in terms of chip area and power consumption as the feature size of analog devices does not directly benefit from scaling. LÄS MER

4. 3. CMOS High Frequency Circuits for Spin Torque Oscillator Technology

   Författare :Tingsu Chen; Ana Rusu; Jerzy Dabrowski; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave integrated circuit; CMOS; spin torque oscillator; Balun-LNA; wideband amplifier; on-chip bias-tee; multi-standard multi-band radios;

   Sammanfattning : Spin torque oscillator (STO) technology has a unique blend of features, including but not limited to octave tunability, GHz operating frequency, and nanoscaled size, which makes it highly suitable for microwave and radar applications. This thesis studies the fundamentals of STOs, utilizes the state-of-art STO's advantages, and proposes two STO-based microwave systems targeting its microwave applications and measurement setup, respectively.
